Specification of Letters Patent.

Patented an. 5, 1915.

Application filed July 5, 1913. Serial No. 777,427.

' To all whom it may concern:

This invention consists in certain new and useful improvements upon thecandymaking machine shown and described in our United States Patent No.1,040,427, dated October 8, 1912, and the primary object of theinvention is to provide a means for causing the vertical shaft to movein unison with the kettle.

In the drawings, Figure 1 is a side elevation of the machine; Fig. 2is'a side elevation on an enlarged scale as compared to Fig. 1, showingthe salient feature of this improvement; and Fig. 3 is a detail lookingdownwardly from the line 33, Fig. 2.

As more fully described in our said prior Patent No. 1,040,427, themachine comprises a post or column 2, arm 4:, and perforated head 5within which head the rotating shaft An arm 22 extends from the wishboneorv yoke 25,. which retains the kettle 23, and when the lever 33 isrocked, the kettleholder 25 and arm 22 are caused to rise and fall inunison. The collar 18 is secured to the shaft 7 and a yoke 20, which isfastened at 21 to the arm 22, engages the collar 18 upon its undersurface and in this manner elevation of the rod 22 causes the shaft 7 tomove in unison therewith. All other parts shown in the drawings anddesignated therein by reference numerals to 50, in-v clusive, areidentical with the correspondingly numbered parts of our said priorPatent No. 1,040,427, and the construction and operation is fullydescribed in said prior patent. v V It has been found by actual practicethat to shift the lever 33 would elevate both the kettle 23 and theshaft 7 in unison, and that when said parts were moving upwardly, theywould move at the same rate of speed; but when the kettle is allowed todrop, as more particularly explained in our said prior patent, theshaft7 would sometimes not descend as readily as the kettle itself,since 1n the machine of said prior patent, gravity alone was relied uponto carry both the kettle and the shaft 7 downwardly; and since the shaft7had more friction to overcome than did the kettle, the shaft 7 would'SOII'lGtlIIlGS bind or stick. In cases where the machine was being usedto cook a batch of candy containing nuts or the like, or for very heavymixtures, the result has been that sometimes the scrapers 43 wouldbecome lifted off the bottom of the kettle and separated therefrom by aspace of half an inch or more, because some nut or similar article wouldcreep in between the bottom I of the scraper and the floors of thekettle.

and where such a result is not attained, a,

layer of candy or candy mixture will collect upon'the kettle, withoutbeing scraped off or removed, which layer would sometimes be burned andthus impair the flavor of the entire batch.

It is the primary object of this invention so to construct the machinethat the shaft 7 1 moves in unison with the kettle, whether the parts bemoving up or down. In the machine of our said prior patent, the shaft 7and the kettle 23 were certain to move in unison when travelingupwardly, but not certain so to move when traveling downwardly; but thisinvention makes it certain that the shaft and the kettle will move inunison, regardless of the direction of. travel.

As best shown in Fig. 2, the collar 18, which is secured by a suitablescrew to the shaft 7, is provided with flange 51.. The yoke 20 which issecured at 21 to the arm 22, engages said collar 18 upon the undersurface just as in our said prior patent, although the yoke may besomewhat different in shape from that depicted in the drawings of oursaid prior patent. Projecting into the yoke 20 is a screw 52 and the bar53 is provided with a slot 54 within which the screw 52 is received. Atits lefthand end the bar 53 bears fingers 55 which reach over the flange51.

Secured to the rod 22 is a bracket 56 to which'the lever 57 is pivotedat 58 and said lever 57 is connected to the bar 53 by the pin 59. Bymeans of the lever 57, the bar 53 may be moved toward or away from theshaft 7 in an obvious manner. When the parts are in the positiondepicted in the drawings, the bar 53 will engage the upper surface ofthe flange 51 and as the rod 22 descends it will carry therewith the bar53, which bar, by pressing upon the flange 51, will surely and certainlycause the shaft 7 to move in unison with the rod 22 and the kettle 23.When the kettle is elevated, the yoke 20 will raise the shaft 7 just asset forth in our said prior patent, and, as will be obvious, thisinvention consists in the attachment of the devices which connect therod 22 to the shaft 7 shown at the top of Figs. 1 and 2.

Whenever the arm 22 is being depressed the bar 53 will bear downwardly,upon the flange 51 and the collar 18 will be between the fingers 55 andthe yoke 20,'thus making sure that the rod 22 and shaft 7 will move inunison, whether travelingup or down; but if the lower end of the lever57 be moved toward the right, Fig. 2, the fingers 55 are carried clearof the flange 51 and the connection between shaft 7 and rod 22 isreleased. Under such circumstances, therefore, the rotating shaft 7 maybe lifted out of the kettle and the operating parts cleaned, adjusted,or repaired. In other words, if the lower end of the lever 57 bethrowntoward the right, the shaft 7 may be raised without regard to themovement or movements of the arm 22; but when the parts are in theposition depicted in the drawin the arm 22 and shaft 7 are lockedtogether at all times.

Ihe precise form of the device for looking the arm 22 and shaft 7together may be varied in an obvious manner, and sundry other changes inthe details of construction may be made, without departing from thescope of the invention or of the various claims.

\Ve claim as our invention:

1. A candy-making machine comprising a kettle, a yoke supporting thesame, a rotating shaft, an arm connected to said kettle-supportingmeans, a collar upon said shaft, means fixed upon said arm, and adaptedto bear downwardly upon said collar, and means for reciprocating saidkettlesupporting means.

2. A candy-making machine comprising a kettle, a yoke by which same issupported,

a rotating shaft, an arm adapted to raise or lower the same, meansconnecting said arm to said kettle-supporting means, a collar upon saidrotating shaft, means upon the arm adapted to bear downwardly upon saidcollar, and means intermediate said lever and said kettle-supportingmeans whereby said lever is adapted to raise or lower said kettleandsaid rotating shaft.

3. A candy-making machine'comprising a kettle, a yoke supporting thesame, a rotating shaft, an arm adapted to raise or lower saidshaft andconnected to said kettle-supporting means, a collar upon said shaft, abar in connection with said arm and adapted to bear downwardly upon saidcollar, and means for moving said bar toward or away from said shaft andbeyond the path of travel of said collar.

4. A candy-making machine comprising a kettle, a yoke supporting thesame, a rotating shaft, an arm adapted to raise or lower said shaft andconnected to said kettle-supporting means, a collar upon said shaft, abar in connection with said arm and adapted to engage one surface ofsaid collar, a yoke secured to said arm and adapted to engage the othersurface of said collar, and means for moving said bar toward or awayfrom said shaft and beyond the path of travel of said bar.

In testimony whereof we hereunto afiix our signatures in the presence oftwo witnesses.
